How to change a String to Hex to Binary and Back To Hex in Java?

Question

I need this for the conversion to PDU format.

Thanks and regards

The assumption cannot be true. It has to be including text. Thanks .

Answer 1

Convert the string to an Integer and then convert it to a hex string (assuming the initial string was a decimal)

int decimal = Integer.parseInt(String initialString);
String hex = Integer.toHexString(decimal);
String binary = Integer.toBinaryString(decimal);

To convert back:
int newDecimal = Integer.parseInt(hex,16);
int newDecimal2 = Integer.parseInt(binary,2);

I hope this helps.
